The first question almost every buyer asks me is some version of the same thing: how much house can I actually afford? Not the number a website spits out in four seconds. The real number, the one that still lets you sleep at night after you have the keys.

I have walked a lot of first-time buyers through this in Seattle, and the honest answer is that affordability is part math, part lifestyle, and part knowing what this specific market is doing right now. Let me show you how I think about it.

Start With the Number Lenders Use, Not the One a Website Shows You

Before you fall for a listing, a lender is going to look at your debt-to-income ratio. That is the share of your gross monthly income that goes toward debt. Most loan programs want your total housing payment at or under about 28 percent of gross income, and all your debt combined (housing plus car, student loans, credit cards) under roughly 36 to 43 percent.

That math is why two people earning the same salary can qualify for very different homes. A car payment and a couple of credit cards can quietly knock a hundred thousand dollars off your buying power.

So the first move is not browsing Redfin at midnight. It is getting pre-approved. A real pre-approval tells you the actual ceiling a lender will fund, and in Seattle it also tells sellers you are serious. I would rather a client know their true number on day one than fall in love with a house that was never in reach.

What a Seattle Mortgage Actually Costs in 2026

Here is where the local market matters. As of mid-2026, the median Seattle home is selling around $861,000, but that number hides a big spread. Single-family homes are closer to $1.1 million, while condos sit near $540,000. Where you land depends a lot on the type of home you are after, not just the neighborhood.

Mortgage rates have been hovering around 6.4 percent and most forecasts have them drifting into the low-6 range through the year. To put that in real terms, every half-point move on rates changes your payment by roughly $250 to $350 a month on a Seattle-priced loan. That is the difference between comfortable and stretched.

And the monthly payment is more than principal and interest. You also have to budget for King County property taxes, homeowners insurance, and, if you are buying a condo or townhome, an HOA dues bill that can run a few hundred dollars a month. I have seen condo dues quietly reshape what a buyer can spend, so always ask for that number early.

Run Your Own Numbers Before You Shop

You do not need a finance degree to get a realistic estimate. Here is the back-of-the-napkin version I walk clients through:

1. Add up your reliable gross monthly income (the steady stuff, not the bonus you might get).
2. Multiply that by 0.28 to find a rough housing payment target.
3. Subtract your estimated property tax, insurance, and any HOA dues from that target.
4. What is left is roughly what you have for principal and interest, which you can back into a price at today's rates.
5. Then stress test it. Could you still make that payment if your rate were half a point higher, or if one income paused for a few months?

That last step is the one most online calculators skip, and it is the one that protects you. Affordable is not the maximum a bank will lend. Affordable is the number that survives a hard month.

Affordability Is About More Than the Monthly Payment

The payment is only half the picture. You also need cash for the down payment and closing costs, which in our area typically run 2 to 5 percent of the purchase price on top of whatever you put down. And you want reserves left over after closing, because a furnace or a roof does not check your bank balance before it fails.

This is also where the condo-versus-house decision gets real. A condo gets you into a great Seattle neighborhood for less up front, but the dues are a fixed cost forever. A single-family home costs more to buy and maintain, but you control the expenses and you build equity in the land. Neither is wrong. It just has to fit your actual budget, not the budget you wish you had.

The Good News for Seattle Buyers Right Now

For the first time in a while, the market is leaning in buyers' favor. Inventory has climbed to around 2.6 months of supply, homes are taking about 11 days to sell instead of going same-day, and the average listing is seeing roughly three offers rather than fifteen. That means more selection and real room to negotiate.

Even better for affordability: incomes across the Seattle metro are projected to outpace home price growth in 2026, the first time that has happened since before the Great Recession. You also have more leverage to ask for seller concessions, like a closing-cost credit or a rate buydown, which can directly lower your monthly payment. Two years ago that was unthinkable. Today it is a normal part of the conversation.

Putting It All Together

Figuring out what you can afford in Seattle is not about chasing the biggest loan you can get approved for. It is about matching a real monthly number to a real life, with enough cushion that the home stays a joy and not a stressor.

If you are starting to think about buying and you want help running your actual numbers, reach out. I would love to sit down with you, look at your income, your goals, and the current market together, and help you figure out what makes sense. No pressure, no sales pitch, just a clear picture so you can make a great decision. That is the kind of work my team at Emerald Group does every day, and it is the part of this job I genuinely love.
